"The incantation for the knockback jinx is 'Flipendo'. This jinx is the most utilitarian of Grade 2 spell, in that it will allow the caster to 'knock back' an opponent or object and can also be used to push and activate certain magically charmed switches. Like many Grade 2 spells, Flipendo can be targeted."
The Standard Book of Spells, Grade 2

The Knockback Jinx[2][1] (Flipendo[2][1]) is a jinx that can be used for a variety of purposes; to physically repel an opponent, knock away an object, to blast apart fragile objects, and activate magically charmed switches.[2] It is covered in both Quentin Trimble's The Dark Forces: A Guide to Self-Protection[1] and Miranda Goshawk's The Standard Book of Spells, Grade 2.

This spell is also common (and useful) in duels and should be a part of any duelist's arsenal.

History

It was covered by Filius Flitwick in Charms class in 1984.[3]

This jinx was taught by Professor Quirinus Quirrell to his first year Defence against the Dark Arts class in 1991; they later used it to defeat the various imps, fire crabs, and pixies residing in Hogwarts Castle, as well as helping to protect themselves against the monsters in the Forbidden Forest[4].

In the second year, students learn how to charge up the spell to more powerful levels (without casting the variations). To do so, one must hold their power in their wand and release their magic when the blue spell turns a strange purplish-red colour. Past this point, the spell will backfire in mid-cast, or fly back to the caster, damaging them somewhat.

Effect

The Knockback Jinx feels like a blow to the chest, knocking its victim back[1], along with "a loud bang."[5]

Defence

The Knockback Jinx can be rebounded to its caster by means of either the Disarming Charm or the Shield Charm, as many other spells can, or simply dodged.

Known uses

"There was a loud bang and he felt himself flying backwards as if punched; as he slammed into the kitchen wall and slid to the floor, he glimpsed the tail of Lupin's cloak disappearing round the door."
—Remus Lupin uses this spell on Harry Potter[src]
Caster(s) Date Notes
Dobby 30 May, 1993 After Lucius Malfoy realised that Harry Potter freed Lucius' House-elf, Dobby, with a sock, Dobby used magic that sent Lucius flying backwards as the latter was about to curse Harry. As this was accomplished by House-elf magic, without a wand,[6] it may not have been exactly the same as a traditional knockback jynx, but the effect was certainly comparable.
Harry Potter 17 December, 1992 Professor Gilderoy Lockhart revised this with his second year class in the 1992-1993 school year for use in duelling.[2] He then had Harry Potter and Draco Malfoy duel each other with it.[2]
Draco Malfoy
Alastor Moody 18 June, 1996 During the Battle of the Departments of Mysteries, Alastor Moody used this jinx to knock a Death Eater off the ground and hit a large rock before disappearing behind it.
Severus Snape June 1997 Used this jinx on Harry Potter when escaping Hogwarts Castle alongside the Death Eaters[7].
Remus Lupin 1 September, 1997 On 1 September, 1997, Harry had this spell used on him once more, this time by Remus Lupin at 12 Grimmauld Place[8].
Draco Malfoy September, 2020 Used in a Duel against Harry Potter in Harry's house.[9]

Etymology

The spell quite simply means "to flip someone onto their end".

Behind the scenes

  • This jinx can be bought at Wiseacre's Wizarding Equipment in Diagon Alley[12].
  • In the films, Everte Statum and Rictusempra are used instead[13].
  • Every time Harry had this jinx used on him, it was because he had called the caster a coward[8][7].
  • A spellbook detailing how to cast this spell could be found in Ollivanders[4].
  • In the Harry Potter and the Philosopher's Stone (video game) Harry can cast this spell on Flipendo Buttons to activate certain mechanisms such as lifting a portcullis or moving flying platforms.[4]
  • In the film adaptations, Stupefy can have the same effects of Flipendo, knocking an opponent over or sending them flying through the air, though it can also simply render the target unconscious or sedated without exerting force on them. The spell also shares similarities with the Disarming Charm, Stunning Spell, Banishing Charm, and Impediment Jinx in its uses to knock down or send a target flying, sometimes to the extent of rendering a target unconscious.
  • In Hogwarts Mystery, the Knockback Jinx is covered in Charms class. This seems unusual, as defensive spells have not been shown as being part of the Charms curiculum, but Defence against the Dark Arts instead. Though jinxes, hexes and curses can be grouped together in a category called Dark Charms.
